Description
Technical field
The present invention relates to a kind of safety of coal mines device, particularly a kind of about the anti-sheet net arrangement of the effective temporary lining that is used for the hacking shed tunnel construction in the tunneling process of colliery.
Background technology
The i iron shed shoring is mainly adopted in the mine development end tunnel, temporary lining has originally just been carried out temporary lining to the heading end top board, and meet head on and two ribs of helping do not have temporary lining, meet head on and two wall cavings of helping (annotate: wall caving is meant the phenomenon of coal under the action of underground, crag generation slump) do not have effective safety management.The coal of meeting head in tunneling process, crag cause the operating personnel to be injured by a crashing object because of exposing outside wall caving easily for a long time, and particularly raise advance wall caving phenomenon is even more serious, and the constructor is injured by it often, and personal safety can not get practical assurance.
Summary of the invention
At the problems referred to above, the objective of the invention is to prevent the sheet net arrangement for the driving hacking shed tunnel under the breaking surrounding rock condition provides a kind of effective temporary lining.
For achieving the above object, the present invention takes following technical scheme: the sheet net arrangement is prevented in a kind of temporary lining, it is characterized in that: it comprises the anti-sheet net and be arranged on two of both sides, tunnel and help anti-sheet net of meeting head on that is arranged on the top, tunnel; Each is described, and the anti-sheet net of meeting head on comprises a shaped as frame skeleton that is welded by steel pipe, tied up the plastic-steel net with iron wire on the described shaped as frame skeleton, described shaped as frame skeleton middle part is welded with a horizontal steel pipe, turning set is provided with a sleeve on the described horizontal steel pipe, vertical welding one down tube in the middle part of described sleeve, the described shaped as frame skeleton top and the down tube other end are welded with a reversion prevention apparatus clamp respectively, and the claw on the two described reversion prevention apparatus clamps is stuck on the forestope, and with instrument described claw is pounded tightly; Each described two helps anti-sheet net to comprise the shaped as frame skeleton that a usefulness steel pipe is welded, described two help to tie up the anti-sheet of a plastic-steel with iron wire on the shaped as frame skeleton of anti-sheet net, described two help to be welded with two iron hoops at interval on the bottom steel pipe of shaped as frame skeleton of anti-sheet net, described two help a side of the shaped as frame skeleton of anti-sheet net to be welded with two protruded tubes at interval, a reversion prevention apparatus clamp is installed on each described protruded tube, the claw of two described reversion prevention apparatus clamps is stuck on the canopy leg, and pounds tightly with instrument.
The concrete quantity of the described anti-sheet net of meeting head on can be used 2 or multi-disc according to the size of the section of meeting head on.
Each side described two helps anti-sheet net to comprise upper and lower two, helps the online described two pairs of iron hoops of anti-sheet fixedly connected by a cottor pin respectively, and then makes two two to help anti-sheet net 2 to link into an integrated entity for upper and lower two described two.
The present invention is owing to take above technical scheme, it has the following advantages: 1, the present invention is owing to be provided with the anti-sheet net of meeting head at the top in tunnel, therefore meet head on to prevent that the sheet net carries out temporary lining efficiently to top board, make the staff under the situation of the top board of permanent support not, can carry out the roof timbering operation more safely.2, the present invention helps anti-sheet net owing to be provided with two in the both sides, tunnel, therefore two helps anti-sheet net that the temporary lining of rib is formed an integral body, stops the deficiency of former temporary lining, has effectively controlled the wall caving casualty accident of rib.3, the present invention's anti-sheet net and two of will meeting head on is helped anti-sheet Netcom to cross the reversion prevention apparatus clamp to be installed in respectively on forestope or the canopy leg, supporting is firm, cover comprehensively, a kind of very effective supporting means are provided for driving hacking shed tunnel temporary lining under the breaking surrounding rock condition, reduced the generation of boring head, driving hacking shed tunnel temporary lining aspect is improved because of coal, crag and wall caving casualty accident.Therefore, the present invention can be widely used in the temporary lining to the driving hacking shed tunnel.

The specific embodiment
Below in conjunction with drawings and Examples the present invention is described in detail.
The present invention includes meet head on anti-sheet net 1 and be arranged on some two of both sides, tunnel and help anti-sheet net 2 of be arranged on the top, tunnel some.
As shown in Figure 1 and Figure 2, each anti-sheet net 1 of meeting head on comprises a shaped as frame skeleton 11 that is welded by steel pipe, has tied up plastic-steel net 12 with iron wire on shaped as frame skeleton 11.Be welded with a horizontal steel pipe 13 at the middle part of shaped as frame skeleton 11, turning set is provided with a sleeve 14 on horizontal steel pipe 13, vertical welding one down tube 15 at the middle part of sleeve 14, be welded with a reversion prevention apparatus clamp 16,17 respectively at shaped as frame skeleton 11 tops and down tube 15 other ends, claw on the reversion prevention apparatus clamp 16,17 is stuck in i iron both sides as forestope 3, with instrument claw is pounded tightly then.Meet head on to prevent that the concrete quantity of sheet net 1 can be according to size use two or the multi-disc of the section of meeting head on.
